JOSEPH F. GLIDDEN, OF DE KALB, ILLINOIS.

SOIL-PU LVlERIZER.

SPECIFICATION forming part of Letters Patent No. 643,408, dated. February 13, 1900.

Application filed July 18,1899; Serial No. 724,240. (No model.)

To all whom, it may concern.-

Be it known that I, J OSEPH F. GLIDDEN, of De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Soil-Pulverizers, of which the following is a specification.

This invention relates to soil-pulverizers,

and has for its object to provide a simple,

strong, and eflicient device for this purpose which maybe readily adapted to varying conditions.

To this end the invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a pulverizer embodying my invention. Fig. 2 is a plan View of the same. Fig. 3 is a detail view, partlyin front elevation and partly in section, of one of the pulverizing-disks, illustrating its attachment to the frame; and Fig. 4 is a plan view of the same.

In the said drawings, indicates a metallic frame which comprises two rearwardly-diverging side bars 11. These side bars are composed of angle-bars having a horizontal flange 12 and a vertical flange 13, and said side bars 11 are united at their front ends by a plate 14, the body portion of which is horizontal, said plate being provided at each side with vertical flanges 15, as clearly shown in Figs. 1 and 2. The body of the plate 14 rests upon the horizontal flanges 12 at the front ends of the side bars 11 and its margins are secured to said flanges, while the upturned flanges 15 abut against the vertical flanges 13 of said bars and are secured thereto. The side bars 11 diverge rearwardly, so as to give the frame 10 a V shape, and the rear ends of the bars 11 are connected by means of a cross-bar 16, which is also an anglebar, and the horizontal flange of which is secured to brackets 17 near each end, said brackets being in turn secured to the side bars 11, on the horizontal flanges of which they rest and to the vertical flanges of which they are riveted or otherwise fastened.

The pulverizingdisks are indicated at 18 and are secured to the side bars 11 in two diverging series, so as to rotate in vertical planes around horizontal axes which are so inclined to the line of draft as to bring the planes of rotation of the disks into a slightlydivergent angle in a forward direction to the line of draft. The disks of the two series are also alternately arranged relatively to each other, as shown more particularly in Fig. 2 of the drawings, and any desired number of disks within the capacity of the frame may be used.

The individual disks are constructed and mounted as shown in detail in Figs. 3 and 4E of the drawings. Each disk consists of a concave body portion 19 of comparatively thin metal, such as steel, the concavities of the disks being directed inward and slightly forward, as shown. In conjunction with this body portion, which is centrally apertured, is employed a bearing-sleeve 20, terminating at one end in a disk 21, to which the body portion 19 is secured by bolts 22. The sleeve 20 has on its face a circular boss or projection 23, which fits within the aperture of the body 19 and serves to more firmly secure the same to the disk. A longitudinal aperture is formed centrally through the sleeve 20 and disk 21 to receive the shaft or axis 24, on which said parts revolve. Said shaft or axis is secured to a bracket 25, having a shoulder 26, against which the adjacent end of the sleeve 20 abuts, and said shaft or axis is of sufficient length to project slightly into the concavity of the disk beyond the face of the boss 23 and to there receive a key27 or other means for retaining the disk and its sleeve on the said shaft. The bracket is provided with a carrying plate or head 28, arranged diagonall y to the body of the bracket and adapted to fit upon the under side of the horizontal flange 12 of the side bar 11 and to be secured thereto by bolts 29.

30 indicates a bent arm, one end of which is secured to the upper side of the flange 12 of the side bar 11 adjacent to each of the disks 18 by means of the same bolt 29 which is employed to connect the bracket 25 thereto. This arm is bent to extend diagonally upward and rearward both at an angle to the horizontal and at an angle to the axis of rotation of the adjacent disk. This arm carries a combined scraper and sharpener 31, consisting of a bar of steel or the like, so constructed as to abrade the cutting edges of the disks when brought into contact therewith, and thus keep the same sharp. This device is adjustably connected with the arm 30 by being clamped against one face thereof by means of a clamping-plate 32 and clampingbolts 33, so that its angle maybe adjusted to cause it to bear properly against the edge of the disk, while at the same time it may be adjusted longitudinally, whereby when that portion thereof in contact with the disk becomes worn a fresh or unworn portion may be brought into operative'position.

The frame 10 carries a drivers seat 34, which is supported by means of a seat-bar 35 from a platform 36, which is itself supported by brackets or posts 37 from the side bars 11.

The frame 10 is supported upon wheels 38, which are adjustably connected therewith, so as to vary the position of the lower edges of the disks relatively to the surface of the soil, and thus control the depth to which they operate upon the same. The rear wheels are supported in the following manner: At each end of the rear cross-bar 16 there is secured thereto an angle bracket, one arm 39 of which extends downward and is provided with a plurality of apertures, while the other arm 39 extends horizontally and is secured to the horizontal flange of the rear cross-bar 16. The axis 40 of the adjacent wheel 38 is carried by a supporting-arm 41, which is adapted to lit against the arm 39 and which is also provided with a similar plurality of apertures. Two or more bolts 42, passing through the apertures of the arms 41 and 39, serve to connect the twoparts together, and by varying the holes through which the bolts pass the vertical position of the wheels 38 may be adjusted in an obvious manner. The forward wheels are carried by a swiveling cross-bar 43, which rests upon the forward ends of the side bars 11 and which is pivotally connected with the front connecting-plate 14 by means of a king-bolt 44. Stop-chains 45 are provided to prevent the swiveling cross-bar 43 from excessive movement. Said cross-bar is provided at each of its ends with an anglebracket having a vertical arm 46, provided with a plurality of apertures, and a horizon tal arm 46*, which is secured to the horizontal flange of the cross-bar 43, said cross-bar being an angle-bar the flanges whereof are arranged vertically and horizontally. The supporting-arms 41 of the front wheels 38 are adjustably connected by means of bolts 42 to the vertical arms 46 in the same manner as those of the rear wheels are connected to the arms 39.

In order to provide for the proper guiding of the pulverizer, the tongue or thills are connected with the swiveling cross-bar 43, and in the present instance I have shown in Fig. 2 a thill connection adapted for use when three horses abreast are employed. In this construction the thills, which are indicated at 47, are secured to eyes 48 on the cross-bar 43 or are otherwise suitably connected thereto. The front cross-plate 14 is provided with a clevis 49, and to this clevis is connected a treblet ree 50, which has mounted thereon the singletrees 51, to which the three draftanimals are respectively attached.

It will be observed that by reason of the foregoing construction a soil-pulverizer of the disk type is provided which is simple in construction and at the same time strong and durable. The frame is strong and rigid, the connections of the supporting-wheels thereto firm and at the same time readily adjustable, and by such adjustment the depth to which the disks operate upon the soil may be readily regulated. The draft connections are such that while the actual strain of the draft is transmitted directly to the frame and wheels the guiding of the entire implement is rendered effective by the connection of the tongue or thills to the swiveling cross bar. The mode of mounting the disks is such that they are firmly connected to the frame in a simple and inexpensive manner, and the disks lie in front of the sleeves to which they are connected, and thereby protect the same, while at the same time their efficiency is not din1inished and the draft not unduly increased. The devices 31 act not only as scrapers to keep the disks clear, and thereby insure a maximum of efficiency by preventing their clogging, but they also serve to keep the edges of the disks sharp, thereby still further increasing their efficiency, and are readily adj ustable, so that they may be placed in that position wherein they will best accomplish their work.

I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefore described, as it is obvious that said details may be varied without departing from the principle of my invention.

I claim 1. In a soil-pulverizer, the combination, with a rearwardlydiverging frame provided with two correspondingly-diverging series of disks, of vertically adjustable supportingwheels for the rear of said frame, a swiveling cross-bar connected to the front of said frame, and vertically-adjustable wheels connected with the ends of said cross-bar, substantially as described.
